- This two-part lab deals with reading numerical data from a binary file named NBdata.bin. The main reason for using binary rather than text files is that they require less memory and are much faster. The program will read the integer data in binary form and calculate two related quantities: the odd geometric, and the even harmonic means. Important: (1) Although the text file is much longer, the program will only read a fixed number of records, N to provide variability for testing purposes. (2) It may be easier to read all N elements from the file and store them into an integer array since the program will need to access them later. (3) The file will contain only positive integers. (4) Prompt the user for this fixed number of elements N to read from the file. This number will be between 3 and 100. (Your program does not need to check the input). Use the format below. Enter N: [...] Part I: Open the binary file named NBdata.bin for readig. The file is stored internally. Prompt the user…Please design the mapper and reducer for the below WordCount problem. WordCount problem: Given an input text file, count the frequency of each word in the file. Please design the input and output pairs for the Mapper and Reducer, use below table for reference. Input Output We get the "WordCount.jar" file by using the above table. It only contains Mapper and Reducer. There is no Combiner and no Partitioner in this program. Please illustrate how the WordCount.jar program works on the below dataset. This text file only contains one line. Dataset: the sound sounds sound. it is the right right, right? Suppose we run the WordCount.jar program on this file. Suppose that the space symbol, and "?" are all used for separating the words. The outputs of the Mapper are Mapper The outputs of the reducer are Reducer Answer: Are the results sorted alphabetically? When was it sorted? 2 27 20 35This is Python Program 5: Improve the file copy program from Lab 9 so that it will make sure the user enters a file that exists. If a file doesn’t exist, the open function will raise the FileNotFoundError. You do not need to check if the destination exists since a file doesn’t need to exist to write it. Instead of copying the content of the source as exact, it only copies non-empty lines and it also prepend each line with a line number. A line is empty if the length of the line stripped of white space from both end is 0. The code segment below shows how to strip white space and getting the length of the string. If the length of the line is zero, the line is a blank line. line1 = " " line2 = " aa " print(len(line1.strip())) # 0 print(len(line2.strip())) # 2 In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that “add-copy.py” contains only non-blank lines from “add.py” and each line in “add-copy.py” is labelled with a line number. Sample run:…
- implementation of Caesar Cipher Using Python Write Code: You are required to implement the Caesar Cipher encryption/decryption algorithm in Python. Remember to implement the algorithm in such a way that it takes a file as input, encrypts it and store in the current directory. This encrypted file must checkable. The implementation must have a decryption procedure which takes the encrypted file from the current directory, decrypts it and store it with some specific name in the current directory. The name should be different from the original file so that it can be verified.You will write a function that can be used to decrypt Dan’s encrypted text. You will be given an open file that contains an encrypted passage from one of the books, and the name of a file containing a wordlist of English words. You need to discover the shift value to use (0-25) in order to decrypt the text. A correct shift value is one that leads to the maximum number of words being found in the English list of words. To find the words in the encrypted text, you must call split(). For a given shift value, convert all letters to lowercase, then try to find each word in the English wordlist. Do not remove any punctuation or symbols from the word: for example, if the word is hello!, then that is the exact string, including exclamation mark, that you should try to find in the English wordlist. Your function should return a string where all letters are in lowercase, and all other characters (newlines, spaces, punctuation, etc.) are retained. Input In each test case, we will call your…In <sys/param.h>, MAXPATHLEN is defined to be 1024 bytes.The for()loop here correctly bounds variable i to < 1023, such that when the loop hasended, no byte past npath[1023] may be written with \0. However, since i is alsoincremented in the nested statements here as ++i, it can become equal to 1024,and npath[1024] is past the end of the allocated buffer space.Then a null byte iswritten into npath[1024], overwriting the least significant byte of EBP.This canbe exploited as a off-by-one overflow.The bug was fixed by Which changing the logic?
- To be done using C programming:Two identical files are given with different names to them. But some characters in the content of the second file are corrupted. Find the line number and their position where those corrupted letter exists as well as Total number of corrupted (error) letters. Examples: Input: File1.txt contains It is fun to code with C File1.txt contains It is fun to code with C# Output: Line Number : 2 Error Position:2 Total Errors:1 Steps Open two file using File pointer in read only mode. Fetch data of file in two char variable one by one until end of file. If variable encounter new line then increment line number and reset position to zero. If variables are not equal then increment number of error and print error line as well as error index.In Python: Build a function that takes a record from your FASTA file as an argument, and returns a count of each amino acid coded for by the codons of the sequence. Keep in mind that because these records are not necessarily in the proper reading frame, so the user should be prompted to select a reading frame (0, +1, +2). You should put some thought into the presentation of your results by your main function, making sure they are clear and readable. The fasta file contains the below: >MD10G1276500 pacid=40089867 polypeptide=MD10G1276500 locus=MD10G1276500 ID=MD10G1276500.v1.1.491…Professor Potter, a punning pedantic, practices puzzling her students. She has left a secret message, of unknown length, encoded in a file for you to unravel. The setup is simple: each line of the file contains one char and one non-negative integer. The key to reading the message is organizing the characters in the proper order. The integer indicates the position of the character within the message. For example: e 2 b 1 a 3 h 5 c 4 spells 'beach' when unraveled. Write a program that will: Ask the user for the name of a file Check to see that the file exists and contains some data. Open and read this file exactly once Using your MessageDecoder class, unravel and display the message Offer to do it again on another file Required classes: You will create and submit 2 classes: MessageDecoder class: Responsible for converting a scrambled message file into plain text. Contains a public method getPlainTextMessage() that returns the String object. The scrambled file must be scanned only once…
- pls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return FalseGoal:Experimenting with AES-128 symmetric key cipher. Note:Using Python programming language that provided libraries for AES. Description:PART 1: write a program that uses AES-128 to decrypt a message. The program should be named "decrypt", and should deal with three files that contain the encrypted text as a stream of bytes, the 128-bit key for decryption stored as a stream of bytes, and the outcome of the decryption, respectively.- To test this program, here's an example of an encrypted message (ciphertext.dat) and its 128-bit secret key (key.dat). PART 2: you will try to use "brute force" to decrypt an encrypted message, where you only have the first 96-bits of the 128-bit secret key (last 4 bytes of the secret key are missing!) The program should be called "findk", and should deal with two files that contain the encrypted text as a stream of bytes and the first 96-bits of the key, respectively. The program should print out on standard output the missing 4 bytes of the key in…Task 5 Write a Python program to combine each line from the first file with the corresponding line in the second file and then save it in a 3rd file.
